Jamie Lee Curtis has never looked better! The actress and Activia spokeswoman, 54, showed off her incredible beach body when she donned a low-cut black swimsuit during a Hawaiian getaway with friends on Thursday, July 25. Curtis, who next appears in the Veronica Mars movie, also wore wet shoes and a silver necklace while wading through the Pacific Ocean.

Though Curtis has admitted to getting plastic surgery in the past, she has since learned to love her looks the older she gets. "Aging is as natural as a baby's softness and scent," the Halloween star wrote in a March 2012 blog for The Huffington Post. "Aging is human evolution in its pure form."

"Genetics are the key to aging," continued the Hollywood veteran, best known known for roles in A Fish Called Wanda and True Lies. "I now resemble both my grandmothers, where when I was younger I didn't see them at all, and if I am now looking at myself with the eye of one who can look back at photos and movies and commercials and miss the good old days, that would be a wasted life. We are ALL going to age and soften and mellow and transition. All of us, if we are lucky enough to make it through this hard life into older adulthood."

Curtis — mom to daughter Annie, 27, and son Thomas, 17, with director husband ChristopherGuest, 65 — has long been an advocate of embracing her natural looks. Covering the September 2002 issue of More, the star asked to be photographed without makeup, a manicure, hairstyling or fancy clothes.

"There's a reality to the way I look without my clothes on," she told the magazine. "I don't have great thighs. I have very big breasts and a soft, fatty little tummy. And I've got back fat. People assume that I'm walking around in little spaghetti-strap dresses. It's insidious — Glam Jamie, the Perfect Jamie, the great figure, blah, blah, blah. And I don't want the unsuspecting 40-year-old women of the world to think that I've got it going on. It's such a fraud. And I'm the one perpetuating it."

In the interview, the Freaky Friday star copped to getting liposuction and Botox — but said neither procedure improved her appearance. "None of it works," she said. "None of it."

"Ten years ago, before anybody did that, I had fat taken from underneath my eyes because I was on a movie and I was puffy," Curtis recalled. "And I remember the cameraman saying, 'I can't shoot her now.' I remember being mortified. And yet, you know what? Nobody tells you if you take fat from your body in one place, it comes back in another place. All of these 'betting' experiences are not without risk. And there is this illusion that once you do it, then you'll be fine. And that's just horsesh-t. I looked worse."
